A GREAM-SEPARATOR.

Specification of Letters Patent.

Patented Jan. 2,1912.

Application filed November 4, 1910. Serial No. 590,735.

To all whom t may concern.'

Be it known that we, JOHN lV. HUDLOW,

of Minneapolis, county of Hennepin, and

State of Minnesota, and JOHN M. CHAPMAN, of Garden City, county of BlueEarth, and State of Minnesota, have invented certain Improvements inCream- Separators, of which the following is a specification.

This invention relates to improvements in centrifugal cream separators,and the objects we have in view are to provide a compact, power-drivenseparator having all of the parts of the mechanism, including thepower-generator, arranged as a unit within a single casing, whereby theseparator bowl may be driven at the desired speed by means of aninternal combustion or explosive en gine contained within said casing,and provided with a clutch arranged to be operated from a point outsideof the casing for connecting said engine with the driving shaft of theseparator bowl.

The invention consists generally in the constructions and combinationshereinafter described and particularly pointed out in the claims.

The accompanying drawing forming part of this specification is avertical section of a cream separator embodying our invention.

In the drawing, 1 represents a suitable casing arranged to contain allof the operating parts of the mechanism by which the centrifugalseparating bowl is driven. This casing may be formed of two separateparts suitably secured together and separated by a horizontal divisionplate 2, forming an upper compartment 3 and a lower compartment 4, andthe lower compartment being preferably provided with a horizontal bottomplate 5. Upon the top of the casing we preferably provide a circularwall 6, within which is arranged a centrifugalseparating bowl 7. Thisbowl is provided with a vertically depending stem 8 which passes througha bearing 9 arranged in an opening in the top of the casing beneaththe'center of the space inclosed by the circular wall 6. The separatingbowl 7 may be' removed and inserted at will, the lower end of the stem 8being provided with a notch that engages a pin 10 in the clutch hub 11.This hub is provided at its l'owei end or bottom portion with a conicalclutch surface 12, and it preferably has arranged within it a spiralspring 13 that is adapted to engage the face of the clutch member 14 forthe purpose of separating the two members of the clutch. The lowerclutch member 14 is preferably provided with a central stem 15 thatextends into a central opening in the clutch hub 11. The clutch member14 is mounted upon or formed integrally with a driving shaft 16 mountedin vertical bearings 17 and 18 in the engine frame 19. Shaft 16 carriesa suitable pinion 20. Thisshaft is capable of being raised or lowered,sliding vertically in the bearings 17 and 18, and at its lower end itrests by a ball bearing 21 upon a movable plug 22. This plug rests uponthe end of a lever 23 pivoted to the casing 24, and extending outside ofthe caslng, is provided with a handle 25 and a vsuitable hook 26. Thishook may be engaged with a spring hook 27 on the casing, thereby lockingthe lever 23 with its inner end in a raised position and holding theclutch member 14 firmly in engagementwith the clutch hub 11, so that asthe shaft 16 is rotated the spindle 8 and bowl 7 will rotate with it.

Mounted upon the horizontal division plate 2 is an internal combustionengine 28 having a suitable frame 19, hereinbefore referred to, thatrests upon and is secured to the said division plate 2. As alreadystated, the bearings 17 and 18 for the shaft 16 are formed upon orsecured to this engine frame and the bearing 18 preferably extendsdownward through an opening in the division plate, into the lowercompartment 4 of the casing. The engine is provided with a cylinder 29horizontally arranged and formed as a part of said frame, or formedindependently therefrom, and secured to the said engine frame 19. Withinthis cylinder 29 is a reciprocating piston 30 of ordinary type providedwith a piston rod 31 that is connected to an eecentrically placed pin32, on a combined gear and fly wheel 33. This combined gear and flywheel is provided with the usual gear teeth which engage the pinion 2Oupon the shaft 16. A stub shaft 34 is mounted in the division plate 2and is provided with a suitable clutch member that engages said flywheel (not shown) in the usual manner for the purpose of starting theengine by hand. This shaft has a beveled pinion 35 that engages acorresponding pinion 36 upon a shaft 37. Any suitable arrangement ofstarting device may, however, be employed.

The engine is provided with the usual inlet and exhaust valves 38 and89, and we preferabl provide a suitable valve stem 40, having a spring41, and engaging a cam 42 upon a cam shaft 43. This shaft is providedwith a gear 44, engaged by a pinion 45 that is rotated by a link 46engaging the crank pin 32. Ve also prefer to provide a suitable timer43, having an adjusting rod 44 extending outside of the casing. Agasolene tank or reservoir 46 is arranged in the top of the casing andis provided with a fuel pipe 47 that eXtends to a carbureter 48, fromwhichv a pipe 49 extends to the gas inlet of the engine. A suitablevalve is arranged in the pipe 47. This is controlled by a valve stem 5()and hand wheel 51. The engine is provided with the usual spark plug 52,and with suitable batteries 53, located in the lower compartment of thecasing and with a spark coil 54. Suitable conductors 55, 56, 57, 58 and59 connect the batteries, the spark coil, the spark plug, the timer anda suitable cut out 60. These electrical connections are arranged in anysuitable manner and need not be described in detail.

In operating the device the internal combustion engine within the casingis started by means of the shaft 37, and, then, by means of the lever23, the clutch member 14 is moved into engagement with the upper clutchmember 11, and thereafter the shafts 16 and 8, and the bowl 7, aredriven at a high rate of speed through the internal combustion enginearranged in the upper compartment of said casing. This engine rotatesthe combined fly wheel and gear 33 and through the pinion 20 drives theshaft 16, and it, through the clutch described, drives the shaft 8 andthe bowl 7. These parts may be driven at any desired speed.

It will be seen that the apparatus is very compact, all of the partsbeing arranged within a single casing, so that the structure forms asingle unit which may be set up at any desired place and by which thedriving shaft of the bowl may be operated at the desired speed bymechanism contained wholly within said casing.

The details of the construction may be varied in many particularswithout departing from our invention.
